It's not difficult to specialize in one major, as long as your grades are among the best and you don't violate any school rules and regulations during your school days, that's all. Then you can submit your application, take the exam and pass after the school informs you. It's not as difficult as expected, but the competition will be fierce, so if you want to change your major, study hard. In other words, you were admitted to any major, and I was transferred. I saw my major. I also wanted to transfer, but after studying for a year, I felt quite good and gave up. In fact, many things can't be said well, so I came first. I suggest you find a professional lesson plan first, but you should study hard after transferring to college. To tell the truth, it's better to fail a subject in college. It's nonsense to hang a subject for fun in college. Good luck.
